Salvation is the free gift of God for anyone who confesses Jesus as Lord and believes in his/her heart that God raised Jesus from the dead. Romans 10:9-10

Salvation is available to us because Jesus became our substitute. Isaiah 53:3-5 

He became sin so that we might be made righteous. 2 Corinthians 5:21 

He became a curse for us on the cross, so that we could be redeemed from poverty, sickness, and spiritual death. Galatians 3:13-14
